stress reliever? even as i put this question through, i am trying this myself..lol

It always helps to randomly do whatever comes to mind, it helps one to feel in control of the environment and relieve stress. The only problem is it is that if other people are around it may be a stressor for them, or they might think you are crazy.

yeah i do it most of the time. Stress reliever no, but sure makes me feel a tiny bit better. It also depends on the song I'm humming, for example if I'm working extra late overtime I'm humming "woman love-missing" songs and that is not a stress reliever lol!
